Hi I am observing my flink jobs is failing with the below error
2021-07-14T12:07:00.918Z INFO runtime.executiongraph.Execution flink-akka.actor.default-dispatcher-29 transitionState:1446 MetricAggregateFunction -> (Sink: LateMetricSink10, Sink: TSDBSink9) (12/30) (3489393394c13fd1ad85136e11d67deb) switched from RUNNING to FAILED on container_e12_1626252668574_0001_01_000005 @ platform4 (dataPort=34313). org.apache.flink.runtime.io.network.partition.PartitionNotFoundException: Partition 73b5c8ee0c6db91027ce081379f64669#6@7c77e83642e1b954a91dd7b49cf3043b not found. at org.apache.flink.runtime.io.network.partition.consumer.RemoteInputChannel.failPartitionRequest(RemoteInputChannel.java:280) at org.apache.flink.runtime.io.network.partition.consumer.RemoteInputChannel.retriggerSubpartitionRequest(RemoteInputChannel.java:198) at org.apache.flink.runtime.io.network.partition.consumer.SingleInputGate.retriggerPartitionRequest(SingleInputGate.java:515) at org.apache.flink.runtime.io.network.partition.consumer.SingleInputGate.lambda$triggerPartitionStateCheck$1(SingleInputGate.java:845) at java.base/java.util.concurrent.CompletableFuture$UniAccept.tryFire(CompletableFuture.java:714) at java.base/java.util.concurrent.CompletableFuture$Completion.run(CompletableFuture.java:478) at akka.dispatch.TaskInvocation.run(AbstractDispatcher.scala:41) at akka.dispatch.ForkJoinExecutorConfigurator$AkkaForkJoinTask.exec(ForkJoinExecutorConfigurator.scala:49) at akka.dispatch.forkjoin.ForkJoinTask.doExec(ForkJoinTask.java:260) at akka.dispatch.forkjoin.ForkJoinPool$WorkQueue.runTask(ForkJoinPool.java:1339) at akka.dispatch.forkjoin.ForkJoinPool.runWorker(ForkJoinPool.java:1979) at akka.dispatch.forkjoin.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:107) Same has been discussed in the old link. But in my case there is hardly any load in the cluster. Can someone suggest what can cause this error? http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/PartitionNotFoundException-when-running-in-yarn-session-td16081.html Thanks,
